Hi Dennis, could you confirm the model number? Is it an HT-R560?

Hello, I am sorry about your issue. Please send your serial number to [email protected] and I will check on your options. Thank you Onkyo USA

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the
speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

Your sound might not be working because the HDMI and optical audio inputs might not be working.

I made the mistake of buying the Onkyo HT-560 and in less than two years all of the HDMI video inputs started intermittently breaking. Sometimes when you selected the channel both the image and the sound would not come though.

Also the rear speakers stopped working from time to time and I have to run the setup again to get them to turn back on.

I am not sure that Onkyo was ready to introduce this technology, it has been a nightmare and my stereo is going to cost almost as much as I bought it for to fix it.

Oh and there customer service was no help, they just told to bring it to an "authorized service center for repair". They had also had no idea where there was one in my city it took them a day to get back to me.

The Onkyo HT-S5100 looks almost identical to the HT-560 not sure if they are different in anyway.

Stay away from Onkyo in the future! I know I will.

My HT-R560 receiver just did the exact same thing... Frustrating. I haven't had it for much more than a year. Any advice?

Have you checked the speaker select switch on the front of the receiver? "A" "B" or "A +B" or "Off". Sounds simple, but it happens! If you still have an issue post a comment and I can help you troubleshoot some more.

Double check that the approtiate speakers (A or B ) are selected.

if you are using an HDMI cable dont expect sound to come out (even thought HDMI carries both audio and video) the onkyo HT-s5100's Receiver is the HT-r560. the 500 models of the onkyo receiver does not allow HDMI to carry both audio and video. it only allows the video signal to pass to the receiver.

if youre using optical for audio w/c is what you need then these are the steps you need to follow.
*first make sure that the optical connections are ok at the back of the receiver.
*make sure that your DIGITAL INPUT is set to either OPT1 or OPT2 whichever optical input you used to connect the optical cable.
*then go to your PS# settings : go to sound settings / audio moutput settings/ select digital out (optical).

then enjoy.....ü

the 7.1 sound not all the movies has that feature and u need to emulate it, doit in the dolby digital ex and the speakers must sound.

try the volume for the SBL or SBL maybe are to low.

decrease the volume for all the speaker less the SBL, SBR and check it out.

Good Luck
